This has also peaked my interested.
Apparently, the ladies that do this as a legit job expect you to get a boner and they are use to it.. so dont go expecting extras!!! but.. I am thinking of booking an intimate wax followed by a punt maybe a massage with extras or a standard AW booking.
Right now, its in my list of things to try, not hit the planning stage. but if you google male waxing you will find loads of providers.
